Tesseract doesn't work with a very simple example

[Felipe Coutinho]

Hello,

I'm a new tess user. I'm trying to test the tess with this very simple text image and I didn't succeed. This was the text that was recognized: vefysiqxe. I used this command line: tesseract C:\Users\felipelc\Desktop\simple.tif C:\Users\felipelc\Desktop\out
What am I doing wrong?

Regards,

Felipe.

I don't think you are doing anything wrong - I tested this with
ScanBizCards (Tesseract 3.01) and I get Very mpxe (note the same
mistake of x instead of l). I think this is yet another example of
Tesseract's poor recognition whenever it has either too little
information about height (as this case, with just two words) or
different font sizes on a page (this is the case that trips Tesseract
most often).

First of all - please read documentation e.g. [1]. It can save your time ;-).

The resolution of your image is too low -- at 96 DPI, any OCR engine
would have problem with it. After rescaling to 300 DPI, Tesseract was
able to recognize it.
